Choosing the ten finalists for our annual Halloween costume contest wasn't easy—we received tons of photos of city children celebrating the holiday in adorable getups (click here to see all of the pictures we received). Scroll through the slide show of our finalists, then help us determine which child will receive four tickets to see Blue Man Group. Readers can vote for their favorite picture through November 17; we'll announce the winner on November 18. We're also hosting a special offer for Blue Man Group tickets through November 24.
